sjg@uunet.uu.ne (Simon J. Gerraty) (11/29/89)
I have a network of mainly Sun's that I hope to bring onto the Internet shortly. Just about everything is ready. I even seem to have in.named running correctly - or at least it seems to keep nslookup happy. My question relates to sendmail.mx (I understand it is just sendmail linked with the resolver rather than YP lookup stuff) and MX records in named's database. I have followed the example in the manual eg. ;domain ttl addr-class MX preferenc mail-exchanger zen.OZ. IN MX 0 sun0.melb.bull.oz.au. *.OZ. IN MX 0 sol.melb.bull.oz.au. Both sol and sun0 are on my ethernet. Sol is my gateway to ACSnet (a local OZ network). Sun0 has a uucp link to zen, but zen wants to appear to be on the ACSnet (ie in domain .OZ). I currently have all this working by using some imaginative stuff in sendmail.cf on both sol and sun0. However the MX record facility seems to be just the ticket. Trouble is I can't seem to make it work. The sum total of information my manuals contain about MX and named in general is "quite small". I have tried running sendmail.mx in address test mode, and it seems to ignore the MX records. I figured this may in part be due to the fact that until I connect to the Internet, my named cannot reach any rootservers. So I tried the following... *.tn.bull.oz.au. IN MX 0 venus.melb.bull.oz.au. and watched the debug output from in.named while I ran /usr/lib/sendmail.mx -bt > 0 user@host.tn.bull.oz.au This is what I got... > datagram from 134.211.128.101, 10 1104 (33) > req: nlookup(host.bull.oz.au) id 512 type=1 > req: found 'host.bull.oz.au' as 'bull.oz.au' (cname=0) > req: answer -> 134.211.128.101 10 (1104) id=2 Local > datagram from 134.211.128.101, 10 1105 (28) > req: nlookup(host.oz.au) id 768 type=1 > req: found 'host.oz.au' as 'oz.au' (cname=0) > findns: No root nameservers? > req: answer -> 134.211.128.101 10 (1105) id=3 Local I even tried host.bull.oz.au. IN MX 0 venus.melb.bull.oz.au. with the same result. I am sure I must be doing something wrong, but I have nothing to refer to. I could work it out *eventually* by lateral thinking and enough experimentation... but I can't help thinking that someone must have sorted all this out before. It could be that I have made some fundamental mistake in setting up named, or that there is just some simple little item missing from my database... Could some kind soul point me at a source of decent documentation? I would appreaciate it greatly. Please e-mail rather than reply to the list. We are not receiving this list at present - we lost our ARPAnet connection in June. +-----------------------------------------------------------------------------+ Simon Gerraty --- ACSnet: sjg@sun0.melb.bull.oz Bull Information Systems --- Internet: sjg%sun0.melb.bull.oz.au@munnari.oz 677 Victoria Street --- UUCP: ...!uunet!munnari!sun0.melb.bull.oz.au!sjg Abbotsford AUSTRALIA 3067 --- Phone: +61 3 420 0927 FAX: +61 3 420 0955 #include <disclaimer> [ imagine something *very* witty here ] +-----------------------------------------------------------------------------+
